Class 9 Lab | GIS Suitability using a Multi-Criteria Evaluation (MCE)

Class 9 Lab preamble:

Step 1:

Rasterize Tool

Result

Note: if the tool produces polygon-like results that appear much different than the image above, re-run the tool.

Batch Processing

Batch Processing Parameters

Check Boolean Result

Step 2:

Raster Calculator

Raster Calculator

Step 3:

Proximity - Raster Distance

Note: this process is memory intensive; expect completion to take upwards to 15 minutes to complete.

Proximity Distance Result

Step 4:

Proximity Result

Step 5:

Raster Reclass Result

Step 6:

Water Reclass Result

Note: here the white and light blue values are better than the dark blue which is distance < 1000m from waterbodies.

Step 7:

Note: the formula will need to be altered to include the correct naming from the batch process hash numbers added to raster_protected_regions and raster_boundary.

Overlay Result

Step 8:

Range Symbolization

Symbolization Result

Invert Polygon for Visual Mask
